When we use FindAncesstor in custom control template for binding internal elements property into its ancestor element, Visual Studio displays data warning messages in output window when binding engine meets unmatched target type during visual tree traversal though it does the proper binding when it receives expected target type during visual tree traversal.
To suppress these data error warning messages, you should mention level of warning message trace in your library class. Here is the simple data error that I am getting when I bind some commands in rich text box.

Got it working easily. Helped me alot! September How will you stop user from going to next page till user clears all validations on this page? Just like it used to happen in aspx pages. As soon as user will click submit button, all client side validators will validate and of any of them fails then user remains on the same page.
Please help October I have a little problem in this validation process. I don't wan't to show user the validation errors red border on controls before they try to save the form. Is there any way I can disable this validation errors on controls till user tries to submit the form? I assume that there is no problem originating from this part.

I thank you very much for your efforts but you are providing me a code that I do not need. The issue is to find why I get this strange System. As I stated above, the code does not provide the same error message when use binding with Markup attribue extension.
I believe the issue is originating from the compatibility of the conversion between string and either Media. Brushes or Media. Colors in user defined classes. Do you have any comment on this issue? Thank you very much for your interest. I am not using either Template or Resource binding so the link you provided does not help me much.
How can I provide you a copy of the code? Well, I have already copied a big portion it to this post, a small part remains, only. I am not sure but I have the feeling that there is a malfunction somewhere in the WPF engine. I will post you the code if you can provide me a link or an adress, or alternatively, I can copy and paste the code here to the forum as small portions. The content you requested has been removed. Ask a question. Quick access.
